NOD32 renewal

I know I'm not the first to ask about renewals, but I have a few questions which I didn't read here before, I think.
My alert (NODscrean) gives no exact date, but just the month of the year, January 2007. How come?

And for the Netherlands as far as I can see, the date of renewal, the moment that you have paid is your renewal date and that can't be adjusted.

Last question:
I purchased NOD two years ago for one machine, but can I adjust that for more machines?
